JAMES B. SLUSSER ANDv WILLIAMA H. MEEOH, OF ROANOKE, INDIANA.

Letters Patent No. 104,070, dated .Time 1 870.

To all whom 'it'may concern.-

Be it known that we, JAMES B. SLUSSER and-WIL- LIAM H. MEECH, of Roanoke, in the county of Huri-A tington and State of Indiana, have invented certain Improvements in Grate and Back for Cooking-Stoves; and we do hereby declare that the following is a full, clear, and exact description thereof reference being had to the annexed drawing. making part of this specieatiomin which- Y Figure 1 is a perspective view of our improved 'grate and back.

Figure 2 is a transverse Vertical section thereof, showing also a portion of the top plate of a cookingstove.. v

Figure 3 is a front elevation, showing the grate in its lowest position.

. The same letters are used in all theiigures to designate identical parts. 'i

This invention relates to cooking-stoves and Our improvements consist in the construction of the fire-box back, and in combining therewith dampers and an adjustable grate, as will more fully lappear from the following specification and claims.

To enable those skilled in the art to make and use our invention, we will proceed to describe its construction and opel-ation.

I n the annexed drawing- A represents the back of' the iire-box of a cookingstove, extending below the grateto rest upon the bot template, and, above such grate., to connect at its ceutral'portion A1 with the top plate D of such stove.

From the portion .A1 to its sides parts are out away from its upper edge, as cleaidy'shown iudotted lines in tig. l, to form two throats or ues through which the llame and other products of' combustion may pass under the kettles.

Heretofore the upper edge of the tire-box hack has been made straight, so as to form one continuous flue between it and the top plate .of the stove.`

This form of construction is objectionable, because it permits much of the heat to pass between the kettles4 and, directly to the smoke-.pipe,`withont heilig utilized.

This waste is prevented by our form of construction. The projecting portion Al, dividing the ilame and heated gases, compels .them to pass under the kettles and around them.

Dampers A2 A2 are pivoted on the part A', extending outward to the sides of the back, and are used to regulate and direct the draught.

B represents the grate, which, in itsgeneral coustruction, may be of anyapproved pattern.

It is suitably attached to the back A by means. of dowel-pins b, formed upon its rear edge, and fitting .into holes in such back, and its front endl is supported on the bottom plate of the stove by reversible legs, fitting in dovetailed grooves in the frontedge of the rrrate. o By reference to figs. 1 and 3 it will be observed that these legs are constructed with an enlarged part, C, and the ends Cand 02, either otlwhich ends fits 1n the dovetailed grooves in the grate, the end C being considerably longer 'than the end C2, so that, ou inserting one end or the other, the grate may be supported by them in a higher or lower position.

The holes a a.' in the back A permitoi` adjustment of the grate at that point of its support.

In burning differents kindsA of fuel 'in the same stove, it is found desirable to have a grate which can be raised or lowered to suit the circumstances 4under which it is to he used, in order to ecouomize in the consumption of such fuel.- When, for instance, wood is used, to obtain the best results, the plate should be closer to the top plate than when coal -is used. For this our adjustable grate provides in a very simple and convenient manner.

What we claim, and desire to secure by Letters Patent, isi 1. The fire-box back A, constructed with the projecting portion A1, substantially as and for4 the purpose set forth.

2. In combination with the back A A1, the dampers A2 A2, arranged substantially as and for the purpose set forth. I

3. The combination of a back, A, adjustable "grat-e B, and reversible legs C O G2, substantially as vand for the purpose set forth.

In testimony whereof we have signed 4our names to this specification in thepresence of two subscribing witnesses.
